Structrure having a mounting means

ABSTRACT

In order to provide a structure for removable attachment to a substantially vertical surface for example of glass, glazed tiles or metal, the structure has a mounting means comprising: suction means ( 1 ) for sealingly contacting a surface, pulling means ( 2 ) being attached to the suction means ( 1 ) for drawing a part of the suction means ( 1 ) away from the surface, so that a partial vacuum is created between the suction means ( 1 ) and the surface. There is a substantially helical or wedge shaped surface on the pulling means ( 2 ) engaged with a corresponding substantially helical or wedge shaped surface of a rotatable member ( 13 ), whereby rotation of the rotatable member ( 13 ) draws the pulling means ( 2 ) and respective part of the suction means ( 1 ) away from the surface. An intermediate member ( 5 ) is provided for engaging a sealing part of the suction means ( 1 ), the intermediate member ( 5 ) supporting the rotatable member ( 13 ). The structure comprises a structural member ( 10 ) mounted in or on the intermediate member ( 5 ), so that the structural member ( 10 ) is not gripped by the intermediate member ( 5 ) or rotatable member ( 13 ). At least part of the rotatable member extends beyond a part of the intermediate member which is adjacent to the rotatable member. There is a friction reducing member ( 11 ) between the rotatable member and the intermediate member. A clip means, possibly also acting as a friction reducing member ( 11 ), can be provided for holding the structural member  18  temporarily in position on the intermediate member  5  during assembly

The present invention relates to a structure having a mounting means forremovable attachment to a surface. The present invention is particularlysuitable for attachment to smooth surfaces, such as glazed tiles,plastic, steel or glass, such as are commonly found in kitchens andbathrooms.

Mounting means for removable attachment to smooth surfaces in kitchensand bathrooms are well known. They typically comprise a suction meansfor contacting a smooth surface, in the form of a suction pad. Britishpatent application no. GB2373019 discloses such a mounting means forremovable attachment to a surface. It comprises a suction means forsealingly contacting a surface and pulling means attached to the suctionmeans for drawing a part of the suction means away from the surface sothat a partial vacuum is created between the suctions means and thesurface. The pulling means comprises a substantially helical surfaceengaged with a corresponding substantially helical surface of arotatable member. Rotation of the rotatable member causes the helicalsurfaces to move over one another, thereby drawing the pulling means andrespective part of the suction means away from the surface. There is anintermediate member for engaging the sealing part of the suction means.The intermediate member supports the rotatable member at a substantiallyfixed distance from the surface in use. There is a contact means (whichis separate from the intermediate member) which extends beyond thesuction means and which is for contacting the surface when in use, sothat twisting moments caused by putting loads on the mounting means canbe transferred directly to the wall surface without going through theintermediate member and therefore without tending to pull parts of thesuctions means away from the wall.

The rotatable member may have a boss on which structural members can besupported.

This is a successful and effective design of mounting means, but anumber of problems have been encountered.

In the first place, a very strong grip can only be obtained if there isa powerful force on the pulling means. However, such forces tend to makeoperation of the mounting means difficult. Further, for maximumstability, it is desired that any structural member mounted using themounting means should be held as close to the wall as possible and thisis difficult with the existing design.

It is desired that the mounting means will not be accidentally dislodgedby sudden loads or impacts applied to a structure which is fixed usingthe mounting means.

It is desired to make the structure easy to assemble.

The present inventor has realised that a structural member can be heldrelatively close to the wall by mounting it in the intermediate member,rather than on the outside of the rotatable member. Further, thestructure can be protected from shock loads by mounting the structuralmember relatively loosely in the intermediate member.

Accordingly, in a first aspect, the present invention provides astructure having a mounting means for removable attachment to asubstantially vertical surface, wherein the mounting means comprises:

-   -   suction means for sealingly contacting a surface, pulling means        being attached to the suction means for drawing a part of the        suction means away from the surface, so that a partial vacuum is        created between the suction means and the surface, there being a        substantially helical or wedge shaped surface engaged with a        corresponding substantially helical or wedge shaped surface of a        rotatable member, whereby rotation of the rotatable member draws        the pulling means and respective parts of the suction means away        from the surface, and an intermediate member for engaging a        sealing part of the suction means, the intermediate member        supporting the rotatable member, wherein the structure comprises        a structural member mounted in or on the intermediate member, so        that the structural member is not gripped by the intermediate        member or rotatable member.

The present inventor has further realised that the operation of themounting means can be made easier if at least part of the rotatablemember is of larger dimension than a part of the intermediate memberadjacent to it, because of the greater leverage obtained. Further, thisarrangement can be retained even when the structural member is mountedin the intermediate member. The user's fingers can still operate therotatable member without getting caught in the structural member.

Accordingly, in a second aspect, the present invention provides astructure having a mounting means for removable attachment to asubstantially vertical surface, the mounting means comprising:

-   -   suction means for sealingly contacting a surface, pulling means        being attached to the suction means for drawing a part of the        suction means away from the surface so that a partial vacuum is        created between the suction means and the surface, there being a        substantial helical or wedge shaped surface engaged with a        corresponding substantially helical or wedge shaped surface of a        rotatable member, whereby rotation of the rotatable member draws        the pulling means and respective part of the suction means away        from the surface, and an intermediate member for engaging a        sealing part of the suction means, the intermediate member        supporting the rotatable member, wherein the structure comprises        a structural member mounted in or on the intermediate member, at        least part of the rotatable member extending beyond a part of        the intermediate member which is adjacent to the rotatable        member in a dimension normal to the axis of rotation of the        rotatable member.

The present inventor has further realised that operation can be madeeasier by inserting a friction reducing member such as a washer betweenthe rotatable member and the intermediate member. This can be obtained,surprisingly, without introducing flexibility or instability into thedesign which could affect its operation.

Accordingly, in a third aspect, there is provided a mounting means forremovable attachment to a substantially vertical surface, comprising:

-   -   suction means for sealingly contacting a surface, pulling means        being attached to the suction means for drawing a part of the        suction means away from the surface so that a partial vacuum is        created between the suction means and the surface, there being a        substantially helical or wedge shaped surface engaged with a        corresponding substantially helical or wedge shape surface of a        rotatable member, whereby rotation of the rotatable member draws        the pulling means and respective part of the suction means away        from the surface, and an intermediate member, for engaging the        sealing part of the suction means, the intermediate member        supporting the rotatable member, wherein there is a friction        reducing member between the rotatable member and the        intermediate member.

The present inventor has further realised that, when the structurecomprises a structural member and a mounting means, the mounting meanscomprising a rotatable member and an intermediate member which areseparable during assembly and which hold between them the structuralmember, assembly can be complicated as the user will have to supporteach of intermediate member, the structural member and the rotatablemember, which can be difficult with only two hands. The inventor hasrealised that a clip means can be provided for temporarily holding thestructural member with respect to the one of the rotatable member orintermediate member during assembly, before the intermediate member androtatable member are sufficiently engaged to provide full support forthe structural member.

Accordingly, in a fourth aspect there is provided a structure having astructural member and a mounting means for removable attachment to asubstantially vertical surface, the mounting means comprising:

-   -   suction means for sealingly contacting a surface, pulling means        being attached to the suction means for drawing a part of the        suction means away from the surface so that a partial vacuum is        created between the suction means and the surface, there being a        substantially helical or wedge shaped surface engaged with a        corresponding substantially helical or wedge shaped surface of a        rotatable member, whereby rotation of the rotatable member draws        the pulling means and respective part of the suction means away        from the surface, and an intermediate member for engaging the        sealing part of the suction means, the intermediate member        supporting the rotatable member, wherein, in use, the structural        member is supported by the intermediate member and the rotatable        member, clip means being provided which is releasably engageable        with at least one of the rotatable member and intermediate        member for holding the structural member thereto during        assembly.

Preferably, the first, second, third and fourth aspects of the inventionmay be combined together. In a structure according to the first, secondor fourth aspect of the invention, a mounting means according to thethird aspect of the invention may be used. The first aspect of theinvention may have a structural member mounted on the intermediatemember, at least part of the rotatable member extending beyond a part ofthe intermediate member which is adjacent to the rotatable member in adimension normal to the axis of rotation of the rotatable member.

In the structure of the first or second aspect of the invention, theclip means according to the fourth aspect of the invention may also bepresent. Any three out of the four aspects may be combined together.Preferably, all four aspects occur together.

Preferred and optional features of the present invention will be furtherdescribed below. Unless otherwise specified, these features apply to allaspects of the invention.

The mounting means of the present invention can be used for engagementwith any suitable surface. Preferably, it is for engagement with asmooth surface. Preferably, the surface is of the type found in kitchensand bathrooms, for example gloss painted surfaces, metal surfaces, suchas aluminium or steel, glass or glazed surfaces such as tiles or plasticsuch as perspex or PVC.

The suction means of the invention preferably comprises a material whichforms a good seal with a smooth surface and is preferably athermoplastic material example PVC or a silicone composition. Thesuction means maybe of any suitable shape, but is preferablysubstantially circular in plan. It may have a slightly domed profile.Preferably, the pulling means is attached to the suction meanssubstantially in the centre thereof.

The sealing part of the suction means comprises that portion of thesuction means which includes a surface which forms a sealing contactwith the smooth surface in use.

The suction means of the invention should form a sealing contact with asmooth surface around a closed figure, for example a circle. The pullingmeans should of course contact the suction means within the spacedefined by the closed figure.

The pulling means of the invention may be integrally formed with thesuction means, however, it is sometimes found that the suction means isformed of a material which is not suitable for forming a pulling means,being too flexible. The pulling means may then be sealingly engaged withthe suction means, for example by a way of adhesive or by a mechanicalfit.

The suction means preferably comprises a sealing surface, for contactinga surface to which the mounting is to be fixed and a second surface,opposed to the sealing surface. The second surface preferably comprisesat least one structure for engaging the intermediate member, so that theintermediate member can be fixed with respect to the suction means. Forexample, the structure may comprise a ridge. Preferably, it is asubstantially continuously extending ridge extending around the suctionmeans. Preferably, it extends in the region of the sealing part.

The rotatable member of the invention may be made of any suitable shape,but is preferable substantially circular in plan. It is suitably formedof a relatively rigid material, such as metal or thermoplastic. Themetal may comprise aluminium or aluminium alloy. It may be cast and/ormachined. It may comprise a thermoplastic material, for examplepolypropylene or polyethylene. The rotatable member is suitably of adiameter of 2 cm or more, preferably 3 cm or more and most preferably 4cm or more.

The rotatable member is preferably of a generally circularconfiguration.

The rotatable member preferably comprises at least one bearing surfacefor sliding over the intermediate member. The bearing surface preferablyengages the intermediate surface through a friction reducing member suchas a washer, as in the third aspect of the invention. The bearingsurface may engage the intermediate surface through the clip means,which may also function as a friction reducing member. The frictionreducing member such as a washer may be formed of any suitable material,preferably, it is formed of a synthetic polymeric material for examplean acetate based polymeric material. It should be able to withstand theloads applied during use. The friction reducing member may have anysuitable shape but is preferably in the form of a laminar material,which is of thickness less than 15 mm, preferably less than 10 mm. It ispreferably substantially circular in plan.

The friction-reducing member may be fixed to the intermediate member orfixed to the rotatable member. It may be permanently fixed or releasablyfixed. For example, it may have a screw threaded bore which is screwedonto the pulling means. There may be resilient structures formed on oneof the friction reducing member and the member to which it is fixed, forexample at least one hook for engaging at least one latch formation.Preferably, the friction reducing member has a resilient formation forengaging in a central hole of the intermediate member. Thesearrangements may allow the friction-reducing member to act as a clipmeans according to the fourth aspect of the invention.

The bearing surface is preferably located at a relatively large radius.Preferably, it is located at a radius at least 1 cm and preferably atleast 1.5 cm. It may be coincident with the outer rim of the rotatablemember. Preferably, however, it is located at a position displacedradially inwardly from the outer rim of the rotatable member by at least1 mm and preferably at least 2 mm. This is so that the bearing partcontacts the intermediate member at a part of the intermediate memberwhich is also displaced inwardly from its edge and which is accordinglystable and strong.

The bearing surface preferably comprises a substantially closed annularsurface. The bearing surface may be a continuous formation with theouter rim of the rotatable member or it may be displaced away from theouter rim of the rotatable member.

The intermediate member is suitably made of a metal or thermoplasticmaterial preferably, it is formed of a metal such as aluminium oraluminium alloy. It may be cast and/or machined. It may be formed ofthermoplastic material such as polyethylene or polypropylene.

The intermediate member contacts the suction means in the seating partthereof, so that the suction means will be firmly pushed into contactwith the surface to improve the seal.

Preferably, the intermediate member comprises at least one formation forengaging a corresponding formation on the sealing means (as discussedabove) to stably locate the intermediate member with respect to thesuction means. For example, the intermediate member may comprise anannular ridge.

Preferably, the pulling means comprises a substantially helical or wedgeshaped surface for engaging the substantially helical or wedge shapedsurface of the rotatable member. Preferably it which projects throughthe intermediate member. The respective substantially helical surfacesmay be of any suitable configuration. They may comprise cam surfaceswhich extend over less than a full circle or they may comprise screwthreads which extend over more than a full circle. They may comprisewedge surfaces, the upper faces of which are substantially straight orflat. The screw threads are particularly preferred as they allow thedegree of movement of the pulling means to be variable. Preferably, thepitch of screw thread is relatively close, making more than four fullturns in a length equal to the diameter, preferably more than six fullturns. This allows particularly fine control of the extension of thepulling means and low turning forces.

Locking means may be provided for fixing the rotatable member in aposition corresponding to the desired extension of the pulling means.However, where a screw thread is used, it may not be necessary toprovide locking means, the screw threads themselves providing sufficientresistance to rotation because of friction.

Preferably, the pulling means comprises a screw threaded member engaginga screw threaded bushing in the rotatable member. Alternatively, pullingmeans may comprise a screw threaded bushing into which a substantiallyscrew threaded part of the rotatable member is engaged.

The travel of the substantially helical surface should be sufficient toallow a sufficiently strong partial vacuum to develop. Preferably, thedistance of travel will be in the range of 1.0-20 mm, more preferably1.5-5.0 mm.

In the present invention, the contact with the surface is preferablyprovided by the suction means only or by the suction means and a part ofthe structure which is mounted on the mounting means. Preferably, theintermediate member and the rotatable member do not contact the surface.

The mounting means of the invention may be of any suitable size. Thesuction means, intermediate member and rotatable member may be each becircular and each of diameter up to about 10 cm, more preferably up toabout 8 cm being most preferably around 3-5 cm in diameter.

The suction means may provide a contact area in the range 20-80 mm²,more preferably 20-40 mm².

According to the first and second aspect of the invention, thestructural member is mounted in the intermediate member. Any suitablestructure may be provided which does not grip the structural member, sothat it can move. The structural member must be able to move in at leastone dimension. There must be at least one degree of freedom of movementwhereby shocks may be absorbed.

If the structural member is only able to move in one dimension, it ispreferable that that dimension is not parallel to the vertical surfaceor, equivalently, the plane of contact of the suction means. This isbecause the forces most likely to dislodge the device from the verticalsurface extend in a direction which is not parallel to the surface andit is desired to be able to move to accommodate such shocks.

The structural member is preferably mounted in or on a part of theimmediate member which, in use, is close to the vertical surface, oradjacent the vertical surface.

By “close” it is meant that the part of the intermediate member to whichthe structural member is attached is closer to the vertical surface, inuse than the outermost part of the rotatable member. Preferably, in use,all or part of the weight of the structural member is transferreddirectly to the intermediate member. Preferably, the weight is nottransmitted through the rotatable member.

The whole weight of the structural member may be taken by theintermediate member. However, it is also possible that, in use, anotherpart of the structural member will contact the vertical surface so thata part of the weight of the structural member may be supported byreaction forces (suitably frictional forces) at the vertical surface.Preferably, the whole weight of the structural member is taken by theintermediate member and the vertical surface together.

The structural member is preferably rigid. Preferably, it is of thesufficient stiffness to be able to carry the weight of at least of aconventional bar of soap or a toilet roll.

The structural member may make resilient contact with the intermediatemember, as long as it is capable of being displaced under light loadsfor example loads in excess of 1 gram force more preferably in excess of5 gram force.

The structural member may be engaged with the intermediate member by anengagement portion which is received in an engagement recess of theintermediate member. The engagement recess of the intermediate member ispreferably larger than the engagement portion of the structural memberin at least one dimension.

There may be more than one engagement member engaged with one or moreengagement recesses of the intermediate member, as long as no engagementportion is rigidly gripped.

The engagement portion may comprise a suitable structure, for examplestub or arm sections. The engagement portion may extend into theengagement recess of the intermediate member and terminate in theengagement recess, or it may extend through the engagement recess. In apreferred embodiment, the engagement recess is a continuously extendingrecess which extends through the intermediate member. This can allow theengagement structure to be slidably mounted on the intermediate member.

The structural member may comprise any suitable structure. It maycomprise a structural member for engaging other structures. However, itis particularly preferred that it comprises at least one of a toiletroll holder arm, a structural component on a shelf, basket or box, or atowel holder.

A stop member may be provided on one of the engagement portion andengagement recess, engagable with a stop surface of the other component.This can prevent the structural member being disengaged unintentionallyfrom the intermediate member.

In a preferred embodiment, the structural member comprises a curved edgeof a basket, the engagement recess being of sufficient size that it willengage with the curved edge and allow the curved edge to slide throughthe engagement recess. In this way, a basket can be mounted adjacent toa corner between two adjacent vertical walls, the position of themounting member being adjusted along the curved edge of the basket tooptimise the support.

The engagement recess of the intermediate member may be closed on atleast one face by at least one of a friction reducing member, a clipmeans or the rotatable member. The friction reducing member may bereleasably fixed to intermediate member as described above. The frictionreducing member which is releasably fixed to the intermediate member mayprovide a clip means. This allows the entire assembly to be separatedinto components which can then be reassembled when required.

In a preferred embodiment, the present invention provides a kit ofparts, comprising at least one mounting means according to the inventionand at least two structural members, each of which is engageable withthe intermediate member to provide a mounting means according to thepresent invention. In this way, a user can select the desired structureand assemble the components appropriately.

The kit may further comprise a plurality of different intermediatemembers, each of which is engageable with a different design ofstructural member.

In a further preferred embodiment, the structural member comprises anengagement portion which is received in an engagement recess formed inthe intermediate member, at least one face of the engagement recessbeing closed by a washer, the washer comprising a screw thread so thatit is engageable with the screw thread of the pulling means. In thisway, the washer can be screwed on to the pulling means to hold theengagement portion of the structural member in the engagement recessbefore the rotatable member is put in position.

The engagement portion may comprise a rod of diameter in the range 3-10mm and the engagement recess may comprise a slot of a diameter which isslightly larger, being for example 2-5 mm larger than the engagementportion.

It is found that the mounting means of the present invention can supportloads of 9-10 kilograms, which extend for a maximum extent of up to 100mm preferably up to 80 mm from a wall, in use.

The clip means of the fourth aspect of the invention may comprise anysuitable design. Preferably, it is for temporarily fixing the structuralmember to the intermediate member. It may be formed of any suitablematerial, for example a resiliently deformable metal formation or aresiliently deformable synthetic material, such as thermoplastic.Preferably, the clip means comprises a contact surface, for holding thestructural member with respect to the intermediate member or rotatablemember and a resilient grip, for engaging a part of the intermediatemember or rotatable member. It is particularly preferred that theintermediate member should comprise a central hole, through which thepulling means of the suction means projects, the engaging part of theclip means engaging in the hole. Preferably, the clip means comprises acentral hole through which, in use, the pulling means will project, aplurality of teeth being formed around the hole, for engaging in thehole of the intermediate member. Preferably, the teeth comprise undercutformations for forming a snap fit engagement with the hole on theintermediate member.

The present invention will be described further by way of example onlywith reference to the accompanying drawings, in which:

DETAILED DESCRIPTION OF THE DRAWINGS

FIG. 1 shows a structure according to the first, second and thirdaspects of the present invention.

It comprises a suction means 1 comprising a silicone rubber disc havinga pulling means 2 projecting from the center. The suction meanscomprises a slight raised portion 3 in the middle which forms a secureconnection between the pulling means 2 and the suction means 1. Thepulling means 2 comprises a screw threaded shaft. The suction means 1further comprises a raised ridge 4 around its perimeter.

There is an intermediate member 5 of cast aluminium alloy. It comprisesa depending skirt 6 which has, on its underside, a ridge, (not shown)which is configured to exactly fit and engage the ridge 4 formed aroundthe suction means 1. There is a central bore 7 through which the pullingmeans 2 of the suction means projects and which does not engage thepulling means. There is an engagement recess in the form of alongitudinally extending slot 8 which extends from one end of theintermediate member 5 to the other. It is of generally cylindrical formwith one face removed. It comprises a Part—arc shaped stop member 9forming a stop. The structural member 10 in FIG. 1 comprises a toiletroll holder arm which is formed of stainless steel rod, the arm having atwisted U-shape. It comprises an engagement portion 11 which is oftubular shape of a diameter smaller than the diameter of the engagementrecess 8. It comprises a stop surface 12 for engaging the stop 9 of theengagement recess 8, so that when in position, the arm 10 cannot beremoved in the axial direction from the engagement slot 8.

A washer of polyacyrylate material is provided. The washer 11 comprisesa central bore 12 which, in the embodiment shown in FIG. 1, fits overthe pulling means 2 which extends through the bore 7 of the intermediatemember 5 and does not engage the pulling means 2.

There is a rotatable member 13 of a generally disc shape. The outer sideof the rotatable member 13 is finished in contours for aesthetic appeal.The underside of the rotatable member is shown in FIG. 2 and comprises aboss 14 having a screw threaded bore 15 which is engageable with thepulling means 2 of the suction means 1. The outer periphery of theunderside of the rotatable member 13 has an outer rim 16 and innerbearing surface 17 which is displaced by about 2 mm from the rim 16.

FIG. 3 shows the mounting means of the present invention assembled. Thesuction means is completely covered by the intermediate member 5 whichthereby protects it. The rotatable member 13 is shown in position. Theouter diameter of the rotatable member 13 is very slightly larger thanthe outer diameter of the top of the intermediate member 5 which isadjacent to the rotatable member. In this way, a user's fingers willnaturally grip the exterior surface of the rotatable member and will notcatch on adjacent parts of the intermediate member 5. It can be seen thestructural member 10 is held loosely in a configuration in which itprojects forwardly from the intermediate member 5.

In use, the mounting means of the present invention is placed, with thecomponents assembled as shown in FIG. 3 with the suction member engaginga wall.

The wall should have a smooth surface, for example being formed ofglass, ceramic gloss paint or metal. The mounting means is pushed firmlyinto contact with the surface to obtain an initial grip then the userrotates the rotatable member 13. As a result, the screw thread 15 movesover the screw thread 2 of the pulling means, drawing the pulling meansoutward away from the wall. As a result, the central part of the suctionmeans is pulled away from the wall to create a partial vacuum betweenthe suction means of the wall, whereby a force is generated which theholds the mounting means in place. The structural member 10 will tend torotate so that an inward portion 17 of the arm 10 will rest against thewall with the outer portion 19 protruding from it.

According to the third aspect of the invention, the washer 11 reducesthe friction between the rotatable member and the intermediate member 5.It also prevents scratching of surfaces between these two members.

According to the first aspect of invention, the arm 10 is heldrelatively loosely in the intermediate member so that any shock loadsapplied to the arm can be easily absorbed without applying twistingforce to the mounting means.

FIG. 4 shows a further embodiment of structure according to the presentinvention in which the suction means, intermediate member, rotatablemember and washer are exactly as shown in FIG. 1 but the structuralmember comprises a substantially circular towel ring 20. The engagementportion of the towel ring will comprise a substantially tubular sectionwith a stop slot exactly as shown for the arm 10 in FIG. 1.

FIG. 5 shows a third embodiment of structure according to the presentinvention in which the mounting means comprising suction means,intermediate member, washer and rotatable member is exactly as shown inFIG. 1 but the structural member comprises an upper circular section rim21 of a basket 22 for containing articles for example for use in thebathroom. In this case, the circular suction rim 21 is configured sothat it has no stop slot corresponding to the stop slot 12 shown inFIG. 1. Accordingly, it can slide along the recess 8. In this way, themounting means can be fixed to a wall adjacent to corner with the basketpushed into the corner at any suitable position.

FIG. 6 shows a sketch isometric view of a clip means, according to thefourth aspect of the invention. The clip means comprises a disk 23 and acentral hole 24, through which the pulling means will project, in use.

The hole is surrounded by eight resilient teeth 25. Each tooth comprisesa wedge shaped leading section 26 with an undercut 27 and a stem 28. Inuse, the clip means of FIG. 6 can be used as the friction reducingmember 11 of FIG. 1. It can perform exactly the same friction reducingfunction if it is made of suitable thermoplastic material. The teeth 25are configured so that, when the clip means is pushed into engagementwith the hole 7 of the intermediate member 5, the wedge section 26 ridesmoothly into the hole. The stems 28 are of such a length that the teeth25 can project all the way through the thickness of the hole 7, with theundercuts 27 clipping behind the rear surface of the intermediate member5. In this way, the clip means will be sufficient to hold the structuralmember, for example 10, in position during assembly. The clip means isformed of thermoplastic material with sufficient stiffness to hold theweight of the structural member during assembly. This will make assemblyof the whole mounting means easy and convenient.

FIG. 7 shows an embodiment of the intermediate member 29 suitable foruse with the structural member 21 shown in FIG. 5. It comprises a slot30, the base of which has an arc shaped profile so that the circularparts of the structural—21 can ride smoothly along the slot 30, allowingthe mounting means to be placed at any desired position on thestructural member. A lightening hole 31 is provided to reduce the weightof the structure.

FIG. 8 shows a rear view of an intermediate member 32. This design maybe applied to the intermediate member shown in FIG. 1 or FIG. 7. Acutaway portion 33 is provided in the side of the formation which, onthe outside of the intermediate member, defines the engaging means forthe structural member. This is in order to allow the suction means tosit comfortably under the intermediate member 32.

FIG. 9 shows a yet further embodiment of intermediate member 34. It isshown engaged with the clip means of FIG. 6. It can be seen that it hasa single hole 35 for engaging the stub of a hook shaped structuralmember 36. Lightening holes 37 are provided to reduce the weight of theformation. It can be seen that the hook is held temporarily so that theintermediate member 34 can be placed position over a suction member 13with the pulling means 15 projecting through the central hole where itcan be engaged with a rotatable member 13 in a simple straight-forwardmanner.

The present invention has been described above purely by way of exampleand modifications can be made within the spirit of the invention whichextends to equivalents of the features described. The invention alsoconsists in any individual features described or implicit herein orshown or implicit in the drawings or any combination of any suchfeatures or any generalisation of any such features or combination.
